Chiral anomalies induced transport in Weyl metals in quantizing magnetic field

Abstract

Weyl metals host relativistic chiral quasiparticles, which display quantum anomalies in the presence of external electromagnetic fields. Here, we study the manifestations of chiral anomalies in the longitudinal and planar magnetotransport coefficients of Weyl metals, in the presence of a quantizing magnetic field. We present a general framework for calculating all the transport coefficients in the regime where multiple Landau levels are occupied. We explicitly show that all the longitudinal and planar transport coefficients show quantum oscillations which are periodic in 1/B. Our calculations recover the quadratic-B dependence in the semiclassical regime and predict a linear-B dependence in the ultraquantum limit for all the transport coefficients.
